diluted with red. The variation in colour of the prothorax 

 would distribute the specimens, in my table ; the female 

 with it bicolorous would go with M . coenosus, which has the 

 elytral margins pale, and the others with M. insignipennis, 

 which is a consistently larger Tasmanian species, with some- 

 what different antennae, and shining elytra. At first glance 

 it resembles M, fumosus and T. ate?', the former has elytral 

 punctures in double series, the latter differs in generic features. 

 Var.(1) A female, also from Cairns, possibly belongs to 

 this species, but has the third to tenth joints of antennae 

 strongly serrated (subpectinate), its colours are as in the tvpe 

 female, except that each shoulder is obscurely diluted with 

 red. Probably, however, it represents a new species. 



Metriorrhynchus mimictjs, n. sp. 



$ ■ Black, tips of elytra brick-red. 



Head with muzzle very short. Antennae rather long, 

 third to tenth joints feebly serrated, third to sixth joints 

 about the same width at apex, the others decreasing in width, 

 eleventh about two-thirds the width of tenth, and slightly 

 longer. Prothorax conspicuously seven-areolato, strongly nar- 

 rowed to middle, hind angles produced but tips rounded off. 

 Scutellum almost truncate at apex. Elytra narrow, slightly 

 dilated posteriorly; with single rows of large, quadrangular 

 punctures, becoming double for a short distance at base and 

 about tips. Length, 7 mm. 



Hob. — Victoria: Belgrave (F. E. Wilson). Type (unique), 

 I. 12271. 



In general appearance strikingly close to the variety 

 haemorrhoidalis of M. rufi/pennis , but the elytral punctures 

 in single series (except for a very small part of the base and 

 of the apex) ; M. paradoxus is somewhat larger, with the sides 

 and more of the apex of elytra reddish, the punctures larger, 

 and the interstices not alternately more strongly elevated, as 

 the third and fifth are on this species. 



Metriorrhynchus minutus, n. sp. 



9 . Black, basal three-fifths of elytra reddish, base and 

 sides of prothorax narrowly and obscurely reddish. 



Head with muzzle short. Antennae rather short, wide, 

 and moderately serrated, most of the joints slightly shorter 

 than their greatest width. Prothorax small, distinctly seven- 

 areolate, slightly longer than apical width, apex slightly 

 produced in middle, front angles rectangular, hind ones pro- 

 duced, but not very actuo. Elytra rather thin ; with single 

 rows of punctures, except on basal fifth, where they are 

 doubled. Length, 5 mm.
